Automatic fire extinguishing cannon and its control method

Abstract

The invention automatic fire artillery and its control method, is composed by the artillery body and the control system, its characteristic is the system is composed by the water supply installment, the flame picture locator, the decoding as well as the computer; The computer control artillery body movement, accepts the fire alarm through the hypothesis procedure, gains the artillery body position and the flame picture information through the angle potentiometer and the flame picture locator, promptly adjusts the artillery body position and the nozzle angle, after aims the artillery body nozzle at the flame surface vanguard, automatically turns on the water pump and the motorized valve,sprays water to the fire point,fights the fire, until the flame extinguishes, this road alarm has already eliminated.The invention automatic fire artillery can linkage with the fire prevention alarm system,the computer automatic control fire prevention artillery to carry on the flame recognition in spatial scope of the hypothesis monitoring, the flame space localization and automatically open the valve spraying of water, suppresses the flame, specially suits to the big space and nobody value defends the situation the fire safe monitoring and save goal, may raise the automated level of the early fire saves goal.

Description

Technical field: [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to an automatic fire-fighting device with electromechanical integration for automatic identification of flames, automatic positioning, automatic water spraying and fire extinguishing and remote communication functions. Background technique: [0002] According to "Optical Technology" (May 2003, Vol. 29, No. 3, pp. 292-294) "Fire Spatial Positioning Method Based on CCD Image" and "Dayang Information Network" (http: / / www.dayoo.com, 2001 April 14) Comprehensive report on "I am world-leading in large space fire research": Existing fire monitors do not have the functions of automatic flame identification, automatic positioning and remote communication. After the device is discovered, the manual start button is used to spray water to extinguish the fire. After the fire is extinguished, it is also necessary to manually control the fire water monitor to stop runn...

[0002] According to "Optical Technology" (May 2003, Vol. 29, No. 3, pp. 292-294) "Fire Spatial Positioning Method Based on CCD Image" and "Dayang Information Network" (http: / / www.dayoo.com, 2001 April 14) Comprehensive report on "I am world-leading in large space fire research": Existing fire monitors do not have the functions of automatic flame identification, automatic positioning and remote communication. After the device is discovered, the manual start button is used to spray water to extinguish the fire. After the fire is extinguished, it is also necessary to manually control the fire water monitor to stop running. This will inevitably delay the best time to extinguish the fire and cause secondary water damage, especially in Unattended tall spaces and areas that require key protection, especially require the installation of automatic fire cannons; The article "Summary of Water Supply Design Demonstration" reported: "The development of fire-fighting water cannon products began in the 1990s in China. One of the key topics of the "Ninth Five-Year Plan" of the Shanghai Fire Research Institute was "development of fire-fighting water cannons", but the water cannons developed by the institute were only one. This kind of remote control water cannon cannot automatically aim at the fire point, nor can it be linked with the alarm system.”

It can be seen that there are still many deficiencies in the control of existing fire monitors, mainly relying on manual remote control, and the system cannot control the fire monitors to automatically align with the flame; The water cannon can prevent the motor from being damaged when it encounters an obstacle during the movement of the nozzle and is forced to stop moving. However, the fire-fighting water cannon provided by this patent is only a manual control water cannon and cannot be operated automatically; however, this The mechanical structure of the fire-fighting water monitor and the drive circuit of the fire-fighting water monitor provided by the patent can still be used in the present invention, but it is necessary to increase the mechanical structure, water supply device, control circuit and control method associated with automatic control to realize automatic water spraying fire extinguishing function
